SURFACE PREPARATION
All surfaces must be free of dirt, loose paint, oil, grease,
wax, soap and any other foreign matter. Clean previously
coated surfaces by washing with a solution of 2 cups
household ammonia per gallon of water and rinse well.
Remove existing mildew with household bleach. DO NOT
MIX AMMONIA AND BLEACH TOGETHER. Rinse
thoroughly and allow to dry.
PREVIOUSLY PAINTED – Old paint is in good, sound
condition should be washed thoroughly with mineral spirits
or xylene. Sand smooth with 80 grit sandpaper and
solvent wipe with mineral spirits or a tack rag to remove
residue. Apply a coat of Marine Coatings Primer For Metal.
If the old paint is in poor condition, remove it with a paint
and varnish remover or by sanding.
ALUMINUM – Lightly sand the surface smooth with #150
grit sandpaper to remove oxidation. Wipe the surface with
mineral spirits or xylene to remove sanding dust and
residue. Make repairs to the surface as necessary. Apply
a coat of Marine Coatings Primer For Metal and allow to
dry 24 hours before application of Marine Coatings
Topside Paint.
STEEL – Abrasive blast to bare metal or abrade with
emery cloth or a wire wheel. Make repairs to the surface
as necessary. Wipe the surface with mineral spirits or
xylene to remove sanding dust and residue. Immediately
apply a coat of Marine Coatings Primer For Metal and

Coatings Topside Paint.
PRODUCT APPLICATION (cont.) .
APPLICATION
Apply when air (ambient) temperature is between 50-90°F
(10-32°C) and the relative humidity is below 85%. Do not
apply on extremely humid days (90% humidity or above)
or when rain is threatening. Do not apply in the late
afternoon outdoors as the wet film may be adversely
affected by dew. When working in cooler temperatures, be
sure the air and surface temperatures will remain at or
above 50°F for at least 4 hours after application.
Mix thoroughly to ensure any settled pigment is re-
dispersed before use. Apply with a high quality brush,
roller, conventional or airless spray. For brush or roller
application, apply full strength. In hot weather, thin with
5% mineral spirits to maintain a wet edge. On large,
smooth surfaces, apply using a short nap or foam roller
cover followed immediately by back brushing. If using
conventional spray application, thin 5% with xylene and
apply one thin, even coat. After four hours, lightly sand
with 150 grit sandpaper and apply a second coat. Always
wipe with a tack cloth immediately after sanding to remove
any airborne dust that may have settled on the surface. If
using airless spray, apply using 1,600-2,400 psi with a
0.013-0.017 inch tip. If necessary, thin up to 5% with
xylene.
DRY & RECOAT
Dry and recoat times are based on 70°F and 50% relative
humidity. Allow more time at cooler temperatures. Dries to
the touch in 1-2 hours, to handle in 4-6 hours, and can be
recoated after 24 hours.
CLEAN-UP
Clean up application tools and equipment with mineral
spirits.
